1: Over-torque detection enabled during constant
speed operation. After over-torque is detected,
keep running until oL1 or oL occurs.
2: Over-torque detection enabled during constant
speed operation. After over-torque is detected,
stop running.
3: Over-torque detection enabled during
acceleration. After over-torque is detected, keep
running until oL1 occurs.
4: Over-torque detection enabled during
acceleration. After over-torque is detected, stop
running.
